s Claims. (01. 242-39) This invention relates to winding machines and more particularly to an improved sizing device for arresting the operation or the machine when the package being wound reachesa predetermined size.

In the present specification and claims the term package is used in a general sense toindicate any form of wound mass and the term yarn" is intended to designate any kind of strand material whether textile or otherwise.

One object of the present invention is to'provide a sizing device for controlling the stopping mechanism of the machine to cause it to act with promptness and precision .to arrest the winding when the package reaches a predetermined size.

Another object of the invention is to provide a device of the type indicated actuated by the movement of thethread-guide away from the axis or the package being wound tojinitiate the operation of the stopping mechanism of the winding machine without causing undue pressure of the guide against the package.

Another object of the invention is to provide a device of the type indicated having a micrometer adjustment for setting it to accurately control the size of the package being wound.

Another object of the invention is to provide a device of the type indicated in the form of an attachment which can be applied to machines 30 now in use without altering the structure thereof.

Further objects of the improvement are set forth in the following specification which describes a preferred embodiment of the invention, by way of example only, as illustrated by the accompany- 35 ingdrawings. In the drawings: I

In the present specification and drawings the invention is described and illustrated as applied to use with a conventional type of winding machine having a positively driven spindle on which the package is wound. It is to be noted, however, that the improved device may be adapted for use with other types of-winding machines and therefore the invention is not limited in its mode of application.

In machines of the present type it is common to provide means for arresting the winding operaof the micrometer adj tion when the package reaches a predetermined size, such means being usually actuated by the movement of the thread-guide away from the axis of the winding-spindle as caused by the increase in diameter .of the package. The thread-guide is usually mounted on a pivoted frame which is counterweighted to hold the guide in close contact with the winding and in previously-used stopping devices wedges or like means are engaged by the guide-supporting frame as the package reaches the desired size with the wedging action operating to release the detent-means which normally hold the stopping mechanism inoperative with power applied to drive the machine. Under present day practice it is desirable for certain purposes, for example, in producing .cops for dyeing, to wind the packages soft, that is under light tension and pressure so that the yarn mass will be porous for the penetration of the dye thereinto. V

For this method of winding it is essential that the thread-guide shall bear against the package with only a light pressure and it has been found that with the usual sizing device the force required to release the det'ents to actuate the stop ping mechanism causes a considerable pressure to be exerted on the guide and by the guide against the package. As a result the mass of yarn in the package is liable to be crushed and the whole package distorted, frequently causing bulging at its ends and displacement of the coils of yarn therein which prevents free delivery of the mate'- rial in unwinding. To obviate this difiiculty and overcome the disadvantages of previously used sizing devices the present invention contemplates the employment of a knock-oil member which is displaced in position by a light, gentle contact of the guide-carrying frame therewith to cause it to be actuated by a going element of the machine to positively release the detents whereby to initiate the functioning of the stopping mechanism. With the present device, practically no pressure is applied to the thread-guide. during the actuation of the stopping mechanism and therefore soft packages may be wound without danger of crushing or distorting the yarn mass therein.

Referring now to the drawings, the machine herein described and illustrated comprises a boxlike frame 2 having bearings for mounting a horizontal winding-spindle 5 on which the package is wound. Journaled in bearings below the winding-spindle 5 is a cam-shaft 8 carrying a helical cam, not herein shown, for reciprocating the thread-guide HI which traverses the yarn on the package. Pivoted on the cam-shaft 6 is a traverse-frame 8 which supports the thread-guide III to adapt it to reciprocate longitudinally of the winding-spindle 5 and to move away therefrom with the growth of the package as it is wound on the spindle. The thread-guide I is fast at the end of a traverse-bar or rod l l which slides in grooves l2 extending longitudinally of the traverse-frame l, and rising from the traverse-frame is a backing plate I! along which the guide slides during its reciprocatory motion.

The traverse-frame 8 carries a thread-bail l4 across which the yarn 1 leads as it feeds through a notch or slot in the thread-guide III, by which it is traversed from end to end of the package being wound. A tension-device, indicated at 1 in Fig. 1, is usually provided for applying resistance to the draft of the yarn as it feeds from its supply to the thread-guide Ill to be dispersed thereby in layers which build up the package onv the winding-spindle Ii. The machine may be driven from any suitable source of power by a belt, gearing or other means and, as herein shown, power is applied to the winding-spindle 5 through a driving pulley l5 and clutch i6 illustrated in Fig. 8 of the drawings. A belt I! connects the driving pulley IS with a motor or other suitable prime-mover to transmit power to the machine. The clutch I6 is fast on the rearward end of the winding-spindle 5 and the driving pulley I5 is slidably engaged therewith to operate the machine, or released therefrom to arrest the winding operation, by means as next described.

Supported in bearings at the top of the machine frame 2 is a horizontal rod or rocker-shaft 20, on the forward end of which is fixedly mounted a starting handle or lever 2|. Fast-on the rearward end of the rod 20 is a two-armed lever 22, shown in detail in Fig. 9, adapted to cooperate with a tapered flange 23 on the end of the hub 24 of the driving pulley 15 to shift the pulley longitudinally of its axis. One 'arm 25 of the twoarmed lever 22 has a beveled face adapted to engage the beveled side of the flange 23 to slide the driving pulley l5 into engagement with the clutch l6; while the second arm 28 has a similar beveled end adapted to engage the opposite beveled side of the flange 23 to withdraw the driving pulley l5 from engagement with the clutch It. The hub 24 of the pulley l5 slides on a sleeve or bushing 21 which is free to rotate on the spindle I, the pulley being keyed to the sleeve by a pingird-slot connection indicated by dotted lines at A pair of radially-extending spring-arms 29 secured to the web of the pulley ii are arranged with their angularly-bent ends adapted to slide over beveled faces 30 at one end of the sleeve 21. These spring-arms 29 have the effect to urge the pulley I5 into engagement with the clutch l6 to release its flange 23 from engagement with the arm 26 of the lever 22 whereby to prevent frictional contact between these parts during the rotation of the driving pulley. The construction and method of operation of the present clutchdevice are the same as shown and described in United States Letters Patent No. 834,778 of October 30, 1906, and will therefore not be described more specifically herein. Sufllce it to state that as the lever 22 is rocked by the rod 20 in a clockwise direction, as viewed in Fig. 9, its arm 25 will cause the pulley I5 to be engaged with the clutch ii to drive the spindle 5; whereas, when the lever 22 is rocked in the opposite direction its arm 26 will act to withdraw the pulley from engagement with the clutch It to release the drive and arrest the operation of the machine.

A helical spring 3| connected to the arm 26 of the lever 22 and anchored at 32 to a part of the machine frame 2 tends to rock the lever to withdraw the pulley from engagement with the clutch It; the lever 22 being rocked in the opposite direction to connect the drive to start the operation of the machine by means of the handle or starting lever 2| on the rod 20. The rod 20 and lever 22 are normally maintained in position with the driving pulley l5 engaged with the clutch it under the control of a pair of detents shown in Figs. 1, 2 and 3 of the drawings. A sickle-shaped arm 35 reaches downwardly from the starting lever 2| and is formed at its end with a shouldered detent 36 adapted to engage a notched detent-shoulder 31 on the upper arm 18 of a pivoted quadrant-shaped lever 40. The lever 40 is pivoted at 4| to the side of the machine frame 2 and its arcuately-shaped portion 42 normally extends in concentric relation to the cam-shaft 8. The under side of the quadrant 42 of the lever 40 is formed with a tapered groove 43, see Fig. 5, which is engaged by the end of a dogging lever 45 pivoted to the traverse-frame 8. The dogging lever 46 acts to resist the return of the traverse-frame toward the winding-spindle 5 after .the guide It! has been forced outwardly therefrom by the growing package, this being a usual form of construction in machines of the present type. A finger-lever 46 connected to the dogging lever 45 may be employed to manually release the latter to permit placing the threadguide against the core of the package to start the winding operation.

-To effect prompt stopping of the machine a brake-disk 4l,'indicated by dotted lines in Figs. 1 to 3, is usually provided on the spindle 5, being adapted to be engaged by a brake-shoe 48 carried by an arm SI of the starting lever 2|. It will be understood that the cam-shaft 6 is driven from the winding-spindle 5 through the means of gearing or a suitable belt, in accordance with the usual construction, and the elements of the machine as above-described are illustrated and described with greater particularity in United States Letters Patent No. 801,941 of October 17, 1905. In this prior patent the means for arresting the operation of the machine when the package reaches a predetermined size consists in a wedge-block or member 49 adjustable along the quadrant 42 of the lever 40 and having a beveled portion adapted to be engaged by a shoulder or ledge 9 on the traverse-frame 8 to lift the outer end of the lever 40 to release the detents "and 31. As before indicated, such a wedging engagement between the traverse-frame 8 and the wedgeblock or element 49 has the eflect to resist con-- tinued movement of the thread-guide away from the axis of the package and thereby causes the guide to exert an abnormal pressure against the package.

The present invention avoids the use of the above-described wedging means by employing a relatively light, pendant, knock-off member, indicated generally by the numeral 55, which is rocked by the traverse-frame 6 to cause it to engage a going part oi the machine to positively lift the lever 40 to release the detents. For the sake of simplicity and to adapt the present device for general application to winding machines in use without alteration in the structure thereof, the standard wedge-element 49 is utilized as an adjustable mounting for the pendant knock-E member 55. As shown in Fig. 5, the element at is preferably constructed of sheet-metal or barstoclr bent at right-angles to overlie the top oi the quadrant n and looped around thereinunder with an upwardly-extending portion engaging in the groove it of the quadrant. A set-screw m threaded through the upper portion of the member W is adapted to be set up against the top of the quadrant ti to hold the member in adjusted position thereon.

Referring more particularly to Figs. d and 'l of the present drawings, the member W is prelerably made in two parts which are adjustable in relation to each other for a purpose later explained. Its main portion consists of a leverarm at having an offset portion at its upper end i'ormed with a hole till ior mounting it on a pivotstud or bearing hub at. The hub ht protects from the side of a disk as in eccentric relation to the axis thereof and has a bore ht which is centered axially of the disk. The hub dd passes through the hole bl in the lever-arm db and is held with its end abutting the side of the element it by means of a screw ti inserted through its bore bill and screwed into said element, see Fig. 5. By releasing the screw ti the disk ht may be turned thereon to vary the position of the axis of the eccentric hub W on which the lever-arm dli rocks; it being noted that the periphery of the disk at is knurled to facilitate this manual adjustment. The depending portion of the leverarm at is twisted at at to position its lower end at right-angles to its main portion and extending laterally from this end of the arm is a projection M which serves merely as a weight to counterbalance the member in its suspension. Projecting forwardly from the hole til in the member bit is an arm 65 having a lug Eli bent at right-angles thereto and formed at its end with a laterallyextending slot bl which serves as the means for connecting the lever-arm b with its companion member.

The companion'member associated with the member 56 is in the form of a cross-arm Hi having its central portion provided with a hole H corresponding to the hole 51 in the lever-arm 55 to adapt it to be arranged alongside oi the latter and pivoted therewith on the hub 58 of the disk 59. At the forward side of the hole ii the arm ill is formed with a laterally-extending lug ii bent at right-angles thereto and adapted to underlie the slotted lug B6 on the lever-arm I6. A screw -15 having a knurled head 16 reaoheadown throughthe slot 61 in the lug 66 with its threaded end screwed into a tapped hole 13 in the lug'iZ and projecting therefrom to receive a check-nut TI. Surrounding the screw 15 and held under tension between the two lugs 66 and 12 is a helical spring 18, the upper end of which bears against a washer 19. With the two parts of the member 55, that is the lever-arm 56 and the cross-arm l0, pivoted on the hub 58 as shown in Figs. 4 and 5 the screw 15 may be adjusted to vary the distance between the lugs 66 and i2 whereby to adjust the position of the arm with respect to the lever-arm 56; after which the nut H is tightened to'iock the parts in fixed relationship. The arm 10 isformed on the under side of its rearward end with an arcuately shaped cam-face or edge 80 adapted to be engaged by the shoulder 9 on the traverse-frame 8 as the latter swings outwardly with the growth in the winding. The arm W is slltted at M and the slltted portion of the metal bent to one side to form a stop 82 which engages against the edge of the member til to locate the arm. with its cam-race Mi in position to be engaged by the shoulder d on the traverse-frame d. The leverarm. 5% of the member 55 is thus supported in angular position extending downwardly and rearwardly towards the cam-shaft b.

Mounted fast on the outer end of the cam-shalt ii is a going member illustrated in the form oi a dislr or wheel at having its periphery serrated or formed with teeth or cogs dd projecting therefrom. The wheel M is a standard part of the winding machine, beingprovided tor the purpose of engaging a stop-lever or drop-wire til pivoted to the end of the quadrant M oi the lever db and normally suspended by the strand of yarn y feeding from the tension-device "l to the threadguide it. When the yarn breaks, or its supply is exhausted, the drop-wire $5 is tilted by the action oi gravity to cause its inner end to engage the periphery of the wheel M. The wheel 83 rotates in the direction indicated by the arrow in Fig. l, and when the drop-wire 85 is engaged therewith it will rock the lever Mi upward to release the detents 36 and all which maintain the driving pulley iii in connection with the clutch iii. The present sizing device operates in somewhat the same manner as next explained.

To start the machine the lever or handle it is rocked in a clockwise direction, as viewed in Fig. 1, to cause the lever 22, see Figs. 8 and 9, to shift the driving pulley it into engagement with the clutch it; the arm 35 of the lever iibeing thereby rocked downwardly to engage its detentshoulder at: with the detent ill on the quadrant lever 4b to maintain the stopping mechanism inactive. During the operation of the machine the yarn y feeds upwardly across the thread-bail it and through the slot or notch in the threadguide it which is reciprocated longitudinally of the spindle ii to traverse the yarn on the package. The cop or package C is usually wound on a fiber or paper tube t secured to the spindle b and as the layers of winding are deposited in place the thread-guide ill is caused to recde .from the spindle with the traverseJrame 8 rockreceding movement of the guide from the spindle I during the growth of the package the traverseframe is prevented from jumping or vibrating by the action of the dogging lever II in the usual manner as well understood by those versed in' the art.

The sizing device forming the subject-matter of the present invention is adjusted to adapt it to be actuated immediately the thread-guide II has moved away from the winding-spindle I a distance corresponding to the desired size of the package, that is, its radial .dimension. For an initial, approximate adjustment of the pendant member II on the lever II the'traverse-frame I is swung outwardly to place the thread-guide I I in a position corresponding to that which it will assume just before the package reaches the desired size. The element ll is then slid along the quadrant 42 of the lever ll to locate the member II in such position that the cam-face or edge I! on the arm III is engaged with the shoulder 8 on the traverse-frame I so that further movement of the traverse-frame will act to rock the arm II upwardly; the element 48 being then fixed in position by tightening the set-screw I0, see Fig. 5. The screw II is next loosened and the disk II rotated thereon to adjust the effective length of the lever-arm II of the member II to compensate for inaccuracies in manufacture of the parts of the device. This adjustment serves to position the lower end of the leverarm II in proper relation to the periphery of the knock-off wheel 83 to insure that when the lever engages the wheel it will not ride up onto the top of-the wheel and remain suspended thereby to prevent it from swinging back under the action of gravity. This adjustment is important, for if the pendant member II is not returned to initial position after the arrestment of the winding upon completion of each package it will fail to act at the completion of the next package wound on the machine.

The final micrometer adjustment of the sizing device is made with the screw II. By tightening or loosening this screw the lugs II and I! on the members II and Ill, respectively, may be drawn together or caused to be spread apart by the spring 18 whereby to locate the lower end of the lever-arm II in such position that it will be quickly engaged by the periphery of the knockoff wheel 83 when the arm III is rocked upwardly by the engagement of the shoulder 9 on the traverse-frame I with the cam-face III of the arm. In other words, this last adjustment sets the device for prompt action immediately the package C has reached its predetermined diameter; the traverse-frame I having then been caused to move outwardly to such an extent that the engagement of its shoulder l with the camface III lifts the arm III to a very slight extent. It will be understood that when the end of the lever-arm II engages the periphery of the wheel I! it will be caught by one of the teeth 84 thereon and thereby the arm I6 is pushed upwardly to lift the quadrant 42 of the lever 40 to release the detents II and 31.

Upon release of the detents II and 31 the spring 3|, see Fig. 9, is energized to rock the lever 22 to move its end 26 into engagement with the beveled side of the flange 23 to withdraw the driving pulley II from the. clutch II. As the lever 22 is rocked under this action the rod II is rocked with it to cause the brake-shoe ll to engage the disk 41 on the winding-spindle I to insure a prompt stopping of the machine. Should the knock-off occur too soon, however, that is before the package reaches its desired size the screw II may be adjusted to locate the end of the lever-arm II farther .away from the periphery of the knock-oil wheel 83. The winding operation is thus arrested immediately the package reaches its predetermined size and due to the pendant or floating suspension of the knock-off member II practically no pressure is applied to the thread-guide iii. In other words, the movement of the traverse-frame 8 as it engages the cam-surface on the arm 10 of the member II is subject to practically no resistance and consequently no pressure is applied to the threadguide iii to cause it to bear too heavily against the surface of the package. Stated briefly, the sizing device operates without increasing the pressure of the thread-guide against the package so that even though the latter may be soft and spongy its shape will not be distorted or the yarn therein crushed and injured.

) It will be observed from the foregoing that the present invention provides a novel and efllcient means for arresting the operation of the winding machine when the package being wound reaches a predetermined size without causing malformationof the package or injury to the material therein. The device is simple in structure, practically proof against derangement or getting out of order, and in its present form of construction it provides an attachment or fitting which may be applied to machines of standard type already in use without change in the construction and arrangement of the main elements thereof.

While the present sizing device is herein shown as embodied in a preferred form of construction, by way of example, it is to be understood that various modifications may be made in the structure and arrangement of its parts without departing from the spirit or scope of the present invention.
